SPECIFICATION forming part of Letters Patent No. 741,770, dated October20, 1903- 7 Application filed May 15,1902. Serial No. 107,427. (Nomodel.) 7

To all whom it may concern.-

Be it known that I, GEORGE F. GONNER, a citizen of the United States ofAmerica, residing at the city of PortHuron, in the county of St. Clairand State of Michigan, have invented new and useful Improvements inConveyer-Ghutes for Pneumatic Blowers, Fans, and the Like, of which thefollowing is a full, clear, and exact specification.

This invention relates to conveyer-chutes for pneumatic blowers, fans,and the like, and especially to means for changing the direction andelevation of the chutes.

Theinvention consists in the matters hereinafter set forth, and moreparticularly pointed out in the appended claims.

As hereinafter described and illustrated,a pneumatic chute embodying thefeatures of the invention is shown in connection with a pneumatic bloweradaptedlfor threshing-machines, the chute itself being adapted for astraw-stacker.

In the drawings, Figure 1 is a view in per spective of a deviceembodying the features of the invention mounted on a pressureblower.Fig. 2 is a central vertical section through the chute.

Referring to the drawings, A represents a pneumatic blower or fan for athreshing-machine of any type or preferred design, which is adapted togather the straw from the discharge of the machine and force it out forstacking. An annular casing a, preferably of cast-iron, at the mouth ofthe outlet a of said blower is connected to the mouth of the blower andforms a base on which the chute is carried. Said base a may be rigidlysecured to the blower proper or, as herein indicated, may be designed tobe supported by independent means,as the frame of a thresher. Said basea is provided with a circular raceway and friction-balls a Seated onsaid base a is a sleeve 13. Said sleeve may be secured to saidbase by afriction-bearing, which preferably is constructed as follows: The lowerend of said sleeve is provided with an outwardly-extending flange b witha depending lip b. The inner face of said lip is grooved to form araceway complementary to the raceway a An annular flange b securelybolted to the lower face of the flange b, is likewise provided with aninner grooved face, which retains the balls a in place and holds thecollar in position. The flanges b and b overlap and closely approach thebase a, so as to form a comparatively tight joint between the sleeve andthe outlet of the blower. Said sleeve, while cylindrical in section, ispreferably so disposed in reference to the outlet a that its axis isoblique to the axis of said outlet. The plane of the upper end of saidsleeve is also oblique to the plane of its lower end. A raceway a isformed in its flanged upper end similar to the raceway a.

Resting on the upper end of. the sleeve 13 is a chute-collar C. Saidchute-collar C may be continuous, but as herein shown, and preferably,consists of two sections a and c, fitted closely at their contiguousends and detachably secured by hinged joints H and H, by means of whichready access may be had to the chute. -A simple and preferred form ofconstruction for said hinges comprises radial lugs h on one sectionmating with corresponding lugs 11 on the other section, pivot-bolts 71being passed through apertures in the lugs. The removal of either boltpermits the chute to be swung on the other bolt. Obviously any form ofhinged joint may be used, although the simplicity of the'one illustratedmakes it preferable. The lower end of the lower section 0 of said collaris preferably provided with a hearing which reduces the friction betweenthe parts and retains the collar against lateral displacement. Adesirable form of such bearing is obtained by forming the section awitha flange o provided with a depending lip 0 whose inner faceregisters with the raceway a and provides a bearing for the collar 0 onfrictionballs 0 A ring D is secured, to the lower face of said lip c bybolts or other suitable means, the inner face of said ring being adaptedto retain the balls 0 in their raceway and to prevent displacement ofthe collar C. The plane of the flange c is oblique to the main axis ofthe collar G. Owing to this disposition of the connecting parts of thecollar and sleeve, the axes of the latter are oblique to each other. Inorder to secure interrotation of the parts, so as to obtain the desiredelevation of the chute, means coacting with said sleeve and collar areselatter at the required elevation.

cured thereto at points convenient for the use of the operator. A numberof devices may be employed for this purpose. The construction hereinshown, which is preferable, is as follows: Gear or rack teeth (1 areformed in the lower face of the collar D and are in mesh with ahorizontal worm E. The latter is secured by the usual means on a shafte, which is journaled in a suitable bracket F, bolted or otherwisefastened to the sleeve B. A convenient means of rotating said shaft isaflforded by a crank and handle G.

The lower end 2' of the main body of the chute I'is secured to the uppersection 0 of the collar 0. Said chute is preferably made of sheet metal,and in adapting it for use as a stacker the chute, as herein shown andillustrated, is provided with an elbow i, so that the main axis of thechute is oblique to the main axis of the collar 0. An important featureof this form of construction is the fact that the base on which thesleeve revolves supports the entire chute without any exterior rigging,the sleeve acting as a rigid and inflexible connection between the chuteproper and the supporting-base. While the joints connecting the partspermit their free interrotation, they maintain the chute rigidly in anydesired position.

From the above description it is readily seen that the chute as a wholemay be readily turned in any direction relative to the lower mouth bysimply rotating the sleeve B upon the ontlet-collar of the blower-outleta, the ball-bearing allowing easy manipulation of the parts. In case itis desired to elevate or depress the chute the relative position of thesleeve and the chutecollar is readily changed by means of the worm andgear, the ball-bearing joint between the two reducing the friction andpreventing cramping of the parts. This rotation of the parts varies theangle between the axis of the collar and the chute, thereby permittingadjustment of the When so placed, the parts maintain their relativepositions without further attention, thereby obviating the necessity ofclutches, stops, or detents.

The construction herein shown does away with the levers, pulleys, cords,and counterweights on the outside of the chute, which are cumbersome andbecome easily displaced or clogged with dirt. The elevatingdevice isintegral with the chute, and the multiplicity of bearings and otherworking parts, which are features of the usual devices employed for thepurpose indicated, are thereby avoided. The worm and gear operatingmeans can be made to give sufficient power to handle any size or lengthof chute desired, and the angle of its elevation can be rapidly andaccurately adjusted. By the use of a single rotatable sleeve furthersimplicity and avoidance of working joints are attained, while thedischarge-pipe can turn freely in any direction Without reference to thesupporting-base.

The joints between the parts are so arranged that the seams are at anacute angle with the line of the blast, thereby minimizing leakage,while the peculiar arrangement of the raceways in the ball-bearingsprecludes the possibility of dust and dirt settling therein.

It will be understood that the details of construction herein shown maybe varied without departing from the spiritof the invention, and I donot limit myself to specific forms and arrangement of parts except asset forth in the appended claims.
